Portal

I downloaded 'Try Anything Twice' from thinkingwithportals.com. The second chamber seems to be broken. Lasers are not going through portals or reflecting properly Has anyone here played it recently, a long shot I know:) Would be good to know if its just me having problems or if the map is broken, possibly by an update

Thanks Darek! I didn't want to regester with TWP just for this, I had to noclip through level 2, kind of a shame, but everything else worked flawlessly. Level 5 is a masterpiece on its own^^ If HMW does get round to fixing ill be sure to replay
